I am trying to transform some non-stationary data into the frequency domain to see if there are any under lying frequencies in the data. a sample of the data can be seen here:(adsbygoogle = window.adsbygoogle || []).push({});

when i look at the data i see a "step" function. I don't know if the fourier transform is the way to go... and was wondering if there was a better transfom to use?
